摘要
简要介绍了自行研制的高压渗透固结仪的主要结构及模拟试验方法，根据模拟试验资料，详细地分析了抽水压密与回灌膨胀过程的基本特征，确定了适用于解释含水层（组）土骨架抽水压密与回灌膨胀（回弹）力学机制的线性粘弹性应力－应变本构律的函数表达式。
The main structure of high pressure consolidation apparatus and the modeling test method developed by authors are briefly introduced in this paper.According to the data obtained by modeling test,the basic properties of the compaction and dilation of the soil skeleton due to pumping and recharge are minutely analyzed .The constitutive function expressions of the stress-strain relationship of soils with viscoelasticity are determined,which are suitable for explaining the compaction mechanism of the skeleton in aquifer(s)caused by pumping and of the dilation (rebound)mechanism resulting from recharging.
